How to use

In Vitro:

Danicopan (ACH-4471) inhibits the proteolytic activity of purified Factor D against its natural substrate Factor B in complex with C3b, blocking production of Bb fragment in a dose-dependent manner with an IC50 value of 0.015 μM. Danicopan (ACH-4471) potently inhibits hemolysis with IC50 values ranging from 0.0040 μM to 0.027 μM (IC90 values from 0.015 μM to 0.11 μM).
